Arduino Pro mini 3.3v nRF24L01+

nRF24L01+ RF Module has small size, which can be intergrated in IoT application. This PCB operates at 2.4GHz, comnunication by SPI protocol, and power is 3.3V

This article will show how to connect it to Arduino Pro mini, make communication between 2 boards.Hardware needed:
1. Two PCB Arduino Pro mini
2. Two PCB nRF24L01+
3. Power 3.3V

1. Arduino Pro Mini

2. nRF24L01+

3. Power module 3.3V

Hardware connection:

Make connection for both Server and Client board.

Software:
There are library call RadioHead which can be download here or here (google share)
After download the library, unzip it, and copy folder RadioHead to Arduino IDE root location (our case is D:\arduino\arduino-1.6.11\libraries\)
